[Mesodermal mixed tumors of the endometrium with a report of 7 cases]

Frequency and characteristics of mixed mesodermal tumors (MMT) and some terminology disparities in the comparatively scarce literature are discussed. The low frequency of MMT described and difficulties in diagnosing have been pointed out. A final diagnosis can be made on operative material only, since curettage contains one (more often the epithelial) of the components of biphase tumorous. The authors emphasize on guided attention to MMT, as well as the necessity of serial sections. The most important factor is depth of invasion.
